National Botanical Garden

When Steve tried to unravel the clues of a mysterious symbol he finds on jars of peanut butter in "Black Mystery Month", he calls the curator of the Smithsonian Peanut Museum who tells him the truth must be revealed. The next day, Steve learns that the curator was mysteriously murdered, leaving a dying blood message saying, "In the elf condom", which the police assume to be "a horny midget who plays it safe." But Steve's selective dyslexia rearranges it to "Find the monocle". He locates the monocle in the curator's clock, which has the symbol on it. Stan shows him a map that he found years ago which can only be read by the monocle Steve recovers. It is a message to find the pole that bore Old Glory, the first stripper at The Filly Buster. At a strip club, Stan assumes that it is a flag but Steve finds out it is actually a pole shaped cane that bore America's first stripper. Using the cane and the monocle in conjunction with the message, it burns up, revealing another message, leading to the National Botanical Garden, finding a big hat like the one on President Peanut. They deduce that they must go to the first "President Peanut" and head to the Lincoln Memorial.
